Answer to Question 1
C
Assess all surfaces exposed to casts, cloth restraints, bandages and dressings, tubing, or orthopedic braces. An external device applied to or around the skin exerts pressure or friction on the skin, leading to skin impairment. When restricted from moving, dependent body parts are exposed to pressure that reduces circulation to affected tissues. Know which patients require assistance to turn and change positions. Patients with limited caloric and protein intake develop impaired or delayed wound healing. Keeping the blood pressure artificially low may decrease arterial blood supply, leading to ischemia and breakdown.

A To determine learning needs, the nurse should assess the patient's previous knowledge level. However, this would not be the most important factor for the nurse to assess first.
